Techniques for going up and down slopes at cable tray bends

Cable tray slopes can be achieved using pre-fabricated adjustable bends, on-site bending techniques, or calculation-based fabrication for precise vertical and inclined routing.

Pre-Fabricated Adjustable Bends

Products like Cablobend EZ allow installers to create vertical and horizontal bends without cutting the tray. These adjustable mesh tray fittings can flex to angles up to 90°, accommodating up and down slopes efficiently. They are available in multiple heights and widths, and include rigidity clips for added strength. This method reduces installation time and enhances safety by minimizing work at height and eliminating the need for cutting tools .

On-Site Fabrication

Wire mesh cable trays can be bent on-site using tools such as bolt cutters or side wall bending techniques. The process involves cutting or bending the tray live at the project site, with protective measures like rubber caps to maintain safety and prevent damage to cables. This method is flexible for custom angles and offsets, especially when pre-fabricated fittings are not available .

Calculation-Based Fabrication

For precise slope and offset installations, tools like the Cable Tray Slope & Fabrication Calculator and Cable Tray Offset Calculator can be used. These calculators help determine V-cut dimensions, slope lengths, hanger spacing, and cut marks for vertical, horizontal, or compound bends. By entering the desired angle, height, and distance, installers can generate accurate fabrication diagrams and measurements, ensuring proper alignment and structural integrity .

Best Practices

• Always secure trays with appropriate hangers and fasteners, following manufacturer guidelines.
• Use paired riser links for vertical bends to maintain stability.
• Consider pre-fabricated adjustable bends for repetitive or high-volume installations to save time.
• For custom or complex routing, combine on-site bending with calculation tools to ensure precise angles and offsets. By combining these methods—pre-fabricated adjustable bends, on-site fabrication, and calculation-based planning—installers can efficiently create up and down slopes in cable tray systems while maintaining safety, accuracy, and structural integrity.
